RESPON TEKANAN DARAH TERHADAP MENTAL STRESS TEST PADA MASYARAKAT YANG TERPAJAN BISING PESAWAT DI SEKITAR BANDAR UDARA

Background: The increased activity of domestic and international flights at the
Adisucipto airport can make noise threshold value (NTV) of the area in Tegaltirto
village, Sleman, Yogyakarta I. D. increases. Measurements were carried out in the
village tegaltirto showed results that were above the safe bastes NTV which has
been determined by the Ministry of Health of the Republic of Indonesia. Increased
NTV rated capable of causing health disorders and neuroendocrine physiological
changes. Aircraft noise as a psychological stressor is capable of inducing an
integrated stress response in the body of people around the airport. Epinephrine is
a hormone that plays a role in the integrated mental stress response and capable of
causing activation of the sympathetic nervous system. Epinephrine will increase
the strength and speed of contraction of the heart and lead to generalized
vasoconstriction thereby affecting the cardiovascular response of the people living
around airports.
Methods: This study using analytic observational design with cross sectional
approach (cross-sectional). This study divided the research subject into two group,
the group that was not exposed to airplane noise (low intensity noise) with groups
exposed to noise due to the activity of the airplane in airport Adisucipto (high
intensity noise). The number of each group is 30 subject and fullfill the inclusion
and exclusion criteria. There are two variables in this study, namely: blood
pressure response and noisy. Blood pressure response is the reactivity value
measured by calculating the difference between the pre-test and post-test of the
mental stress test. Blood pressure was measured with a non-invasive method using
digital sphygnomanometer. The data obtained then processed statistically using
the program SPSS version 15.0 for Windows evaluation only. Data hypotheses
were tested using the Mann-Whitney method when the data is considered were not
normal distributed according the Kolmogorov-Smirnov method, and using
independent-t test when data were normally distributed.
Result: Mann-Whitney test results on the value of systolic reactivity (delta)
indicates the value of high noise intensity group (22.68 ± 9,35 mmHg) was
significantly higher (p 0,05) had higher
scores than the low noise intensity group (80,34 ± 11,38 mmHg). Post-test
diastolic pressure value high noise intensity group (94,67 ± 15,3 mmHg) after
mental stress test were significantly (p
